* Seed: A seed is a mature ovule, a structure produced by flowering plants and gymnosperms that contains the potential for a new plant. It acts as a protective package and food source for the developing embryo.
* Embryo: The embryo is the tiny, undeveloped plant inside the seed. It consists of:
* Radicle: The embryonic root, which grows downward and anchors the plant.
* Hypocotyl: The embryonic stem, which connects the radicle to the cotyledons.
* Epicotyl: The embryonic shoot, which will eventually develop into the leaves and stem.
* Cotyledons: Seed leaves that provide nourishment to the embryo during germination.
How they are related:
* The embryo is the heart of the seed. Without an embryo, the seed is essentially empty.
* The seed provides everything the embryo needs to start growing. This includes:
* Food reserves: Stored in the cotyledons or endosperm (a nutrient-rich tissue surrounding the embryo).
* Protection: The seed coat surrounds the embryo, shielding it from damage and desiccation.
* Germination: When conditions are right (moisture, temperature), the embryo inside the seed begins to grow. This process uses the food reserves in the seed to develop the seedling into a mature plant.
In essence: The seed is like a capsule or container that houses the embryo and provides it with everything it needs for its initial growth. The embryo is the future plant, waiting for the right conditions to sprout and begin its life cycle.
